The territory of Svalbard is extremely northern, and is subject to both the polar night and the midnight sun. The capital, Longyearbyen, is home to nearly eighty percent of the country's population. Other settlements include Sveagruva, Ny-Ålesund, and the Sámi settlements of Ođđa-Romsa and Davve-Norga. Barentsburg is the country's only remaining Russian settlement, and Russian is an official regional language there. The country has ten islands with significant area; the largest and only inhabited island is Spitsbergen.
